Detailed Description

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The vertical indoor unit includes casing with air inlet and air outlet, evaporator set between the air inlet and the air outlet, and the air entering the casing will pass through the fins of the evaporator and be blown out from the air outlet. When the evaporator works, the temperature of the surface of the evaporator changes, and the air flowing through the surface of the evaporator is influenced, so that the effect of adjusting the outlet air temperature is achieved. A volute tongue component is arranged between the evaporator and the air outlet and is used for forming an air duct communicated with the evaporator and the air outlet. The volute tongue component is provided with two openings, including an inner opening opposite to the evaporator and an outer opening opposite to the air outlet. The cross-flow wind wheel of the vertical indoor unit is arranged in the air duct and is usually fixed with the volute tongue component for driving the air at the inner opening to transfer to the outer opening by rotating at a high speed so as to form the air blown out to the air outlet.

The vertical indoor unit is usually placed on the ground, and after the vertical indoor unit is installed in place, the axis of the cross flow wind wheel of the vertical indoor unit is usually vertical to the ground (the error of plus or minus 10 degrees is allowed), namely the vertical indoor unit is longitudinally arranged; the outlet is generally in the form of a longitudinally extending strip. The area covered by the wind blown out from the wind outlet is in a longitudinally extending strip shape and gradually diffuses in the wind outlet direction. The outer contour of the normal human body is basically in a strip shape extending longitudinally when the human body stands, and the air outlet coverage area of the vertical indoor unit is matched with the occupied space of the human body when the human body stands, so that the wind area of the human body is increased, and the change of the body surface temperature of the human body is accelerated.

The whole shell of the vertical indoor unit can be in a circular column shape, a semi-column shape, a rectangular column shape or a multilateral column shape. The housing is generally divided into a front case, a rear case, a top case and a bottom case, and is combined to form a column.

The vertical indoor unit can be divided into a single through-flow cabinet, a double through-flow cabinet and a multi-through-flow cabinet according to the number of air channels, the number of through-flow wind wheels and the number of air outlets in the vertical indoor unit. Wherein the single cross flow cabinet machine is provided with an air outlet, an air duct and a cross flow wind wheel; the double cross-flow cabinet machine is provided with two air outlets, two air ducts and two cross-flow wind wheels; similarly, the multi-through-flow cabinet machine comprises a plurality of air outlets, a corresponding number of air ducts and a corresponding number of through-flow wind wheels.

Several specific embodiments of the indoor unit of the stand will be mentioned hereinafter, each of which will have one or more modifications. The improvements in one embodiment can be applied to other embodiments without interference.

The invention provides a double through-flow cabinet, and figures 1 to 4 show an embodiment of the double through-flow cabinet.

Referring to fig. 1 and 2, in the present embodiment, the vertical indoor unit includes a casing 2000 installed on an upper side of a machine body fixing seat 1000. The upper side of this point should be understood as the upper side of the center of the housing 2000 on the center of the body fixing base 1000, and this case should include the case where a part of the housing 2000 is flush with the body fixing base 1000, or the case where a part of the housing 2000 is inserted into the body fixing base 1000. The body mount 1000 may include a chassis and other mounting members mounted on or integrally formed with the chassis; wherein, the chassis can be disc-shaped, polygonal disc-shaped or other shapes; other mounting members may be a mounting seat for mounting the casing 2000 or a mounting seat for mounting the compressor, etc.; the present embodiment is described in detail by taking the chassis as a disk. Typically, the chassis is supported on the ground after being installed in place; the lower surface of the chassis can be provided with anti-skid blocks so that the vertical indoor unit can be stably supported on the ground, and the lower surface of the chassis can also be convexly provided with idler wheels so that the vertical indoor unit can move on the ground.

The housing 2000 is formed with an air inlet 2100 and an air outlet 2200, and the air outlet 2200 is in the shape of a strip extending longitudinally. The housing 2000 may be formed separately or integrally; the overall shape of the housing 2000 may be a cylindrical shape, but may be a polygonal cylindrical shape. In the present embodiment, a case 2000 which is provided separately and has a cylindrical shape is taken as an example to explain in detail.

In the housing 2000, an evaporator 3000, a volute tongue assembly 4000 and an air outlet frame 5000 are sequentially arranged from the air inlet 2100 to the air outlet 2200. A cross-flow wind wheel 4100 extending longitudinally is arranged in the volute tongue assembly 4000, the air outlet frame 5000 is connected between the volute tongue assembly 4000 and the air outlet 2200, and the air outlet frame 5000 and the volute tongue assembly 4000 form an air duct communicated with the air inlet 2100 and the air outlet 2200. The evaporator 3000 and the volute tongue assembly 4000 are fixed to the machine body fixing seat 1000, and a driving device is further disposed in the casing 2000, and drives the air outlet frame 5000 to rotate relative to the machine body fixing seat 1000 and to rotate back and forth around a rotation axis extending in the longitudinal direction. Namely, the air channel comprises an air starting section for starting air and a swing section for swinging air; the volute tongue assembly 4000 forms the wind-starting section, and the wind-outlet frame 5000 forms the wind-swinging section.

In this embodiment, the cross-flow wind wheel 4100 is longitudinally arranged to correspond to the longitudinally extending air outlet 2200, so as to avoid the wind generated by the cross-flow wind wheel 4100 changing direction through a large angle and generating a large wind energy loss. Compared with the conventional vertical indoor unit in which the volute tongue assembly 4000 is directly connected with the air outlet 2200, in this embodiment, the air outlet frame 5000 capable of rotating relative to the machine body fixing seat 1000 is connected between the volute tongue assembly 4000 and the air outlet 2200, so that the air outlet angle of the air swinging section of the air duct can be changed by rotating the air outlet frame 5000, and a larger air sweeping angle can be obtained.

Wherein, the air-out frame 5000 can be connected with the casing 2000, and also can be connected with the volute tongue component 4000.

When the air outlet frame 5000 is connected with the housing 2000, the connection mode may be fixed connection, integral connection or movable connection. When the air-out frame 5000 is fixedly connected or integrally connected with the housing 2000, the housing 2000 and the air-out frame 5000 move together. As can be seen from the foregoing, the casing 2000 may be separately arranged, and when the casing 2000 is separately arranged, the front casing of the casing 2000 and the air-out frame 5000 may be fixed to move together, and the rear casing of the casing 2000 and the machine body fixing seat 1000 may be fixed to remain stationary. When the air-out frame 5000 is movably connected with the casing 2000, the casing 2000 can move relative to the machine body fixing seat 1000 by following the rotation of the air-out frame 5000; or can be static relative to the machine body fixing seat 1000 and rotate relative to the air outlet frame 5000; or the housing 2000 can be driven by another driving device to be stationary, moving or linked with the air outlet frame 5000 relative to the machine body fixing seat 1000. The air outlet frame 5000 and the housing 2000 may be connected to each other by sliding through an arc-shaped sliding rail structure or by swinging through a swing link structure.

When the air outlet frame 5000 is connected with the volute tongue assembly 4000, the connection mode can be movable connection or fixed connection. When the air outlet frame 5000 is movably connected with the volute tongue assembly 4000, the air outlet frame 5000 and the volute tongue assembly 4000 can be connected by adopting a pivoting or sliding scheme.

Preferably, an air duct sealing structure is arranged between the air outlet frame 5000 and the volute tongue assembly 4000 and used for keeping the air duct sealed when the air outlet frame 5000 rotates relative to the volute tongue assembly 4000, so that air leakage when the air outlet frame 5000 rotates relative to the volute tongue assembly 4000 is avoided. The air duct sealing structure can be respectively formed on the air outlet frame 5000 and the volute tongue component 4000, and the sealing effect can be achieved through mutually matched sealing surfaces; the air duct sealing structure can also be an intermediate piece with deformability, which is connected between the volute tongue assembly 4000 and the air outlet frame 5000, and is respectively connected with the volute tongue assembly 4000 and the air outlet frame 5000 through two ends of the intermediate piece with deformability, so that the air duct sealing structure can adapt to the relative motion of the air outlet frame 5000 and the volute tongue assembly 4000, and can keep in contact with the air outlet frame 5000 and the volute tongue assembly 4000 to achieve a sealing effect. The deformation capacity can be that a plurality of plate pieces which cannot be deformed are movably connected with each other, and the deformation is realized by the movement or rotation of the movable connection part; or by a connector which is inherently deformable, for example of silicone material.

Preferably, the duct sealing structure includes a duct sealing surface 5100 formed on the air-out frame 5000, the duct sealing surface 5100 is adjacent to the duct and is attached to the volute tongue assembly 4000, and remains attached to the volute tongue assembly 4000 when the air-out frame 5000 moves. Compared with the scheme that the air outlet frame 5000 and the volute tongue assembly 4000 are connected through the middle piece, in the embodiment, the air outlet frame 5000 and the volute tongue assembly 4000 are directly attached, so that parts needing to be assembled can be reduced, the number of parts is less, and the assembly is simpler. In this embodiment, the air duct sealing surface 5100 of the air outlet frame 5000 is in an arc surface shape with the axis coaxial with the longitudinal rotation axis, so that when the air outlet frame 5000 rotates around the rotation axis, the distance between the air duct sealing surface 5100 and the air outlet frame 5000 is unchanged, and a good sealing effect can be generated.

Preferably, the air duct has longitudinal side walls parallel to the axis of the cross flow wind wheel 4100. The air duct sealing structure comprises an air guide connected between the air outlet frame 5000 and the volute tongue component 4000, a movable air guide surface is formed on the air guide 6000, and the movable air guide surface is connected between the air outlet frame 5000 and the volute tongue component 4000 and used for forming the longitudinal side wall together with the volute tongue component 4000 and the air outlet frame 5000. Wherein, the wind guide 6000 can be a multi-plate hinge element, and generates deformation through the rotation of the hinge joint; the wind guide 6000 may also be formed by connecting two plates through sliding grooves, and the deformation is generated by the sliding of the connecting part of the sliding grooves. In this embodiment, the air guide 6000 is connected between the air outlet frame 5000 and the volute tongue assembly 4000, so that the structure of the volute tongue assembly 4000 and the air outlet frame 5000 is prevented from being complicated due to excessive consideration of mutual sealing, that is, the volute tongue assembly 4000 and the air outlet frame 5000 are prevented from being difficult to manufacture and having high manufacturing cost.

Preferably, the air guide 6000 comprises a first portion 6100 and a second portion 6200, the back ends of the first portion 6100 and the second portion 6200 are respectively connected with the air outlet frame 5000 and the volute tongue assembly 4000, and the adjacent ends of the first portion 6100 and the second portion 6200 are movably connected to deform when the air outlet frame 5000 moves; the first portion 6100 and the second portion 6200 form the movable air guiding surface towards one side of the air duct. The movable connection can be hinged connection or chute connection. In the present embodiment, the air guide 6000 is described in detail by taking two portions (the first portion 6100 and the second portion 6200) as an example; of course, in other embodiments, the air guide 6000 may be composed of three, four or more parts.

Preferably, the first portion 6100 and the second portion 6200 are connected in an articulated manner, which has the effect of being flexible and not easy to be locked. Of course, in other embodiments, more intermediate pieces may be connected between the first portion 6100 and the second portion 6200, thereby forming a chain. Of these, the first portion 6100 and the second portion 6200 are preferably plate-like members, i.e., similar to a folding screen. When the air guide 6000 is formed by using two portions, i.e., the first portion 6100 and the second portion 6200, the deformation posture is more easily controlled with respect to three portions, four portions, or the like.

Preferably, when the air outlet frame 5000 moves, the opening of the included angle formed between the first portion 6100 and the second portion 6200 always faces the air duct. Compared with other embodiments in which the opening of the included angle formed between the first portion 6100 and the second portion 6200 faces away from the air duct, this embodiment can prevent the first portion 6100 and the second portion 6200 from invading the air duct, so that the ventilation area of the air duct is reduced, and the wind resistance of the air duct is increased.

Preferably, the housing 2000 includes a rear housing 2300 and a front housing 2400 movably connected to the rear housing 2300, the air inlet 2100 is formed on the rear housing 2300, and the air outlet 2200 is formed on the front housing 2400. The front shell 2400 is connected with the air outlet frame 5000 and used for following the movement of the air outlet frame 5000. Wherein, the front shell 2400 can be fixedly connected or movably connected with the air outlet frame 5000.

If the front housing 2400 is fixedly connected to the air outlet frame 5000, the front housing 2400 and the air outlet frame 5000 move together and remain stationary. Such as a threaded, snap-fit or integral connection.

If the front housing 2400 is movably connected to the air outlet frame 5000, the front housing 2400 may move synchronously with the air outlet frame 5000 and remain stationary, or may move asynchronously with the air outlet frame 5000 and generate relative movement. For example, a locking buckle is arranged on the front shell 2400 and the air outlet frame 5000, when the locking buckle is buckled, the front shell 2400 and the air outlet frame 5000 move together, and when the locking buckle is loosened, the front shell 2400 and the air outlet frame 5000 can move relatively; for another example, if the front case 2400 is driven by a driving device to control the moving speed and direction, the front case 2400 and the air-out frame 5000 can be controlled to move synchronously or relatively.

Preferably, a connection sealing structure is provided between the front housing 2400 and the rear housing 2300 to ensure that the front housing 2400 is sealed with the rear housing 2300 during movement. And a sealing structure coupled to maintain the sealing when the front case 2400 rotates with respect to the rear case 2300, thereby preventing air leakage when the front case 2400 rotates with respect to the rear case 2300. The joint sealing structure may be formed on the front case 2400 and the rear case 2300, respectively, for example, by sealing surfaces that are engaged with each other to achieve a sealing effect; the coupling sealing structure may also be a deformable intermediate member coupled between the front case 2400 and the rear case 2300 and coupled to the front case 2400 and the rear case 2300 through both ends of the deformable intermediate member, respectively, so as to achieve a sealing effect in which the relative movement of the front case 2400 and the rear case 2300 is accommodated and the front case 2400 and the rear case 2300 are maintained in contact. The intermediate piece with the deformation capability can be formed by mutually movably connecting a plurality of plate pieces which cannot be deformed per se and realizing deformation through movement or rotation of the movable connection part; or by a connector which is inherently deformable, for example of silicone material.

Preferably, the connection sealing structure includes a connection sealing surface 2410 formed on the front case 2400, and the connection sealing surface 2410 is attached to the rear case 2300 and maintains the attachment to the rear case 2300 when the outlet frame 5000 moves. This embodiment has the effect of having fewer parts and simple assembly, as compared to sealing between the front case 2400 and the rear case 2300 using an additional intermediate member.

Preferably, the front case 2400 includes a first panel 2420 and a second panel 2430, the first panel 2420 is connected between one end of the rear case 2300 and the air-out frame 5000, and the second panel 2430 is connected between the other end of the rear case 2300 and the air-out frame 5000; the first panel 2420 and/or the second panel 2430 are movably connected to the air outlet frame 5000, so as to move relative to the air outlet frame 5000 to open or close the air duct.

The first panel 2420 and the second panel 2430 may be straight panels or arc panels, and preferably, the first panel 2420 and the second panel 2430 adopt arc panels, so that the first panel 2420 and the second panel 2430 can keep fit with the rear housing 2300 when moving, thereby obtaining a better sealing effect. When the first and

second panels

2420 and 2430 are flat plates, the left and right ends of the rear housing 2300 need to be bent toward the front side, so that a cavity for accommodating the evaporator 3000 and the scroll volute tongue assembly 4000 can be formed between the rear housing 2300, the first and

second panels

2420 and 2430.

Compared with the scheme of arranging a movable door specially used for opening and closing the door, the embodiment adopts the first panel 2420 and the second panel 2430 to form the front shell 2400, and the first panel 2420 and the second panel 2430 can move relatively to form the air outlet 2200 or close the air outlet 2200, so that the effect of the movable door is achieved.

Certainly, in other embodiments, a door body may also be disposed on the front shell 2400, the door body is movably disposed on a side of the air outlet frame 5000 opposite to the volute tongue assembly 4000, and the door body moves between a door opening position and a door closing position; the air duct is closed when the door body is located at a door closing position, and the air duct is exposed when the door body is located at a door opening position. The structure has the advantages of single function and more convenience in manufacturing and assembling. In the case of separately providing the door body, the first panel 2420 and the second panel 2430 may be fixedly connected to the air outlet frame 5000, for example, integrally formed, screwed, or clamped, so that the air outlet 2200 is always formed between the first panel 2420 and the second panel 2430.

The top mounting plate 7200 and the bottom mounting plate 7300 of this embodiment can both support the volute tongue assembly 4000 and the evaporator 3000; it also has the effect of forming two lateral side walls. In this embodiment, the top mounting plate 7200 and the bottom mounting plate 7300 have the advantage of being rich in functionality. Of course, in other embodiments, two connecting plates may be disposed on the volute tongue assembly 4000 and the air-out frame 5000, so that two lateral sidewalls are formed by the connecting plates; for example, the two connecting plates are connected with the volute tongue assembly 4000 or the air outlet frame 5000 and are connected between the volute tongue assembly 4000 and the air outlet frame 5000.
